A force of P = 20 N is applied to the cable, which causes the 175-kg reel to turn without slipping on the two rollers A and B of the dispenser. Neglect the mass of the cable. Each roller can be considered as an 18-kg cylinder, having a radius of 0.1 m. The radius of gyration of the reel about its center axis is kg = 0.42 m.

The position of the head and neck and the forces acting on the head are shown in the figure. The center of gravity of the head of mass m=9 kg is located at point C. The joint reaction force of F J = 150 N, which makes an angle of α = 30° with the vertical from the point B, is acting on the skull by the neck extensor muscles. The center of the atlantooccipital joint is located at point B. For this flexion position of the head, the neck muscle force FM, which makes an angle of γ with the horizontal from the point A , is effective . (Take the gravitational acceleration g as 9.81 m/s 2. ) Accordingly; a) Calculate the angle γ of the muscle force F M with the horizontal. b) Calculate the muscle strength F M.
